Zinfra wins major contract on West Gate Tunnel Project

Zinfra has been awarded the major power utility relocation work through CPB Contractors and John Holland’s Joint Venture, the construction contractor appointed to build the West Gate Tunnel.

This is an enabling
piece of work for the project, with Zinfra engaged to deliver a significant
amount of work on the AusNet portfolio. This includes realigning the AusNet
220kv transmission line assets which run along the West Gate Freeway, allowing
the widening of the current freeway and the greater project to get underway.

Preliminary works commenced early March, with completion due end of November this year.

The contract
includes lattice tower decommissioning, to be replaced with a combination of
monopoles and new lattice towers, and reconductoring of the lines. A critical
component of delivery will include the substantial freeway crossing of the West
Gate Freeway with a line span reaching approximately 325 metres over existing
traffic lanes, with the freeway kept operational during peak periods. The 220kV
line will then feed into AusNet’s Brooklyn Terminal Station (BLTS).

“It also
demonstrates our ability to engage in collaborative client relationships to
meet current market demands, while mobilising a large team of highly skilled
transmission linesmen to meet project needs,” he said.

The win is also a significant step forward for Zinfra as it extends its expertise, scale and end-to-end service offering on utility infrastructure in adjacent sectors across Australia.
